Alpha Grip taking pre-orders

Pre-orders, previously a bastion of console games, have now started happening with hardware. The makers of the Alpha Grip have opened a page taking pre-orders. According to the press release, they will start manufacturing the devices once they have 5,000 pre-orders. I guess this is a legitimate approach for something that otherwise might be claimed as vaporware.

One question I have – how are you meant to grip the device while at the same time depressing various buttons on the back-side with your fingers? I can only imagine gripping with your palms while keeping your fingers mobile would result in a lot of wailing and gnashing of teeth.
